What this means

claude:haiku

Whole-genome Illumina sequencing of D. melanogaster from Genome Analyzer IIx, generating 17 million reads at 37× coverage with moderate base quality (83.8% Q30). This WGS dataset supports variant discovery applications, though quality metrics suggest careful variant filtering is advisable.

How this grade was computed

Weighted mean of 4 scored metric(s) → 90/100

The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published WGS thresholds, weighted by its importance; nothing is hidden or subjective.
